400+ hp naturally aspirated v6?
Is it possible to build a v6 from a camaro v6 block to over 400 hp? I know there is options like changing th heads , cam changes, piston, etc. what are other ways that there are to do that other than forced induction. I saw Porsche made a flathead 6 making 475 hp...sonit hads to be possible for us to do...I was just wondering where someone would start...for around 6 grand in pocket

On e85 and full bolt on you might get to 380-390 crank.

you'd have to go lightweight and high rev's...so probably best in a flathead config, rather than V.
you're only other option is a massive bore and stroke ...which would probably just not work. |

What all is full bolt ons entail? If our motor was to also be bored out and stroked..how much better would it be power wise? Would ou be able to break into the 420 hp range ?

Full bolt on would be intake, larger throttle body, ported/filled manifold, and maybe a more free flowing exhaust (probably won't do much). You'd have to have a dialed in tune on e85 too. That would most likely put you at 320-325 whp.

It would be an interesting project but i'll be honest OP your looking at what you spent on the car to get to the 370-380whp mark without some form of nitrous or FI..

When y’all are talking numbers of hp and tq, is that to the rear or and the crank?

i just look at it like this, if you need 1.5atmo's to boost rwhp by 100hp then that means to do the same without boost or changing fuel and all other things being equal, you'd need to increase the amount of air processed by the engine by 50% over stock. That means either increasing the volume by 50% or increasing the rpms such that 50% more air on avg is being consumed. I highly doubt you'd be able to do the former with the lgx block, much less make it last. The latter has a chance, if you dumped crazy cash to turn the lgx into an F1 screamer since according to my rough math, that would put the target rpm at over 10k.
for a boost of 100hp with the lgx, you either need to change fuels or boost. Those are the most practical routes. |

How many threads are you going to start for your theoretical and hypothetical and non existent upgrades? I’m not trying to be a dick here but come on man. You ask the same question posed differently with different parts constantly.

Does it matter? Wether or not he asks the same question over again he clearly gets different input and people responding and he has the balls to ask and continue to wonder if it's possible. 400whp N/A without massive engine overhauls is unlikely but the worse crime would be not aspiring to get there. Us 2.0T guys are already pushing our limits and have done a ton of crazy theorycrafting and execution for awesome results. OP you keep doing you jist know what your getting into when you decide to pull the trigger.

The V6 has 4 overhead cams and the heads have integrated exhaust manifolds. I don't believe anybody is making cams or heads for the V6 due to the low demand and high start-up costs. The integrated exhaust manifold means no headers. I don't believe anybody is making an aftermarket intake manifold for the V6 either. So for the moment there don't seem to be many FBO options for the V6. I think FI is the only option if you want big power with the V6.
